At first neither Namecoin nor any alternative domain name system intends to "hijack ICANN". The goal is to establish generally an alternative domain name system. If you whish to extend the decentralization you can host your website content on decentralized webhosting such as
ZeroNet. Your concept of establishing territorial subnets (so far your concept "Back to the federalism of the internet") is of course diametrically against the intentions of a free and uncensored internet and also completely contradictory to your own intentions. You want a free internet but propose a hardly restricted and controlled internet. Russia is going to create such a territorially controlled internet, as China does, as North Korea does. If you worry about corrupted main stream operating systems: Take
Knoppix, starting just from CD. And let's take e.g. one of the Russian DNS servers providing .bit resolution as mentioned, accessed from USA. As you can actually see with
a trace router of your choice the route runs via Italy, UK, then one data center in Russia until you reach your destination. If one of the internet nodes would block your request for which reason ever another route would be taken. As I explained now several times there's no way for a government to control all ISPs or data centers of the world. If this is still not enough take a Namecoin full node and run it with your local ncdns application resolving the .bit domains as it has been provided since the creation of Namecoin.
The fundamental difference is that we have different views of the extent to which governments can intrude.
Also it isnt clear what you mean by federalism of the internet.

My view starts with the notion of territorial subnets because of my estimation of the extreme governments will go to in order to maintain control.
My goal would be anybody could say anything, no restrictions on speech whatsoever, so long as nobody is forced to listen.
There is currently no country on the planet where that is possible though. It doesnt matter whether it is .bit or .com, some speech will bring the government down on a person in any country.
The first practical step in global free speech is local free speech. It is illegal in the United States to advocate the overthrow of the U.S. government, but not illegal to advocate the overthrow of the Venezuelan government.
And....if you make a website advocating the overthrow of the U.S. government, and it is perceived as a threat, the website will disappear....vs....if you make a website advocating the overthrow of the Venezuelan govt your domain is very safe. Doesnt matter if it is .bit or .com
Regarding federalism of the internet, everybody has some specific freedom that they are aware that they lack.
Remember back in the days of the USSR, people harshly seasoned by famine and war, they used to promote freedom from hunger, etc as liberties.
You will never find anybody outside your born twin that shares exactly the same view of liberties as you. There is not, and should not be, an enforced freedom that offends local tradition. That is another colonialism.
The start has to be local freedom not intruded on by geographic outsiders. The U.S. should not have any say over what websites can exist in Venezuela.
TLDR Namecoin should facilitate a free internet first in those geographical areas where the freedom is overtly lacking. There have been past conversations on this thread about, for example, a browser plug in that seamlessly surfed both ICANN and .bit addresses. You could open your browser, land on a page that had .bit and .com addresses, and click on either to go to the page. Once that facility got some usage in a country where it had practical political value, its use would seep into other countries organically.
